Dual-channel nano-carbon-liquid/liquid junction electrodes for multi-modal analysis: redox-active (dopamine) and non-redox-active (acetylcholine).

We present here a dual-channel nanoelectrode to detect both redox-active and non-redox-active analytes. The dual-channel nanoelectrode was developed from theta nanopipette. We developed one channel of the theta nanopipette to be a carbon nanoelectrode and the other channel to be a nano interface between two immiscible electrolyte solutions (nanoITIES) electrode, producing a nano-carbon-ITIES platform.

Interface between Two Immiscible Electrolyte Solutions Electrodes for Chemical Analysis.

The interface between two immiscible electrolyte solutions (ITIES) plays vital roles in various fields, such as neuroscience, environmental science, analytical chemistry, separation, catalysis, and nanoparticle synthesis. ITIES emerges as a unique approach in chemical analysis due to its sensitivity to both redox-active and redox-inactive analytes. Neurotransmitters, metal ions, drug molecules, and other complex molecules such as proteins have been detected using ITIES.

Detection of Acetylcholine at Nanoscale NPOE/Water Liquid/Liquid Interface Electrodes.

The interface between two immiscible electrolyte solutions (ITIES) has become a very powerful analytical platform for sensing a diverse range of chemicals (e.g., metal ions and neurotransmitters) with the advantage of being able to detect non-redox electroactive species.

Assessment of otolith function using vestibular evoked myogenic potential in women during pregnancy.

Introduction: More than 50% of pregnant women experience dizziness frequently in the first two gestational trimesters. During pregnancy, the changes in the metabolism of hormones are responsible for the ovarian cycle resulting in either peripheral or central vestibular alterations. The need for the study is to focus on the effect of changes during pregnancy on the vestibular evoked myogenic potential, an electrophysiological measure that investigates functions of the otolith structures.

Test-Retest Reliability of Cervical and Ocular Vestibular Evoked Myogenic Potential With Simultaneous and Sequential Recording.

Purpose Simultaneous recording of cervical (cVEMP) and ocular (oVEMP) vestibular evoked myogenic potentials aids in reducing the testing time when compared to conventional sequential recordings. The purpose of this study was to examine the test-retest reliability of sequential and simultaneous acquisitions of cVEMP and oVEMP. Method cVEMP and oVEMP were recorded in 35 normal-hearing individuals.
